基于文献计量分析近11年土壤有机碳的研究进展
Research progress of soil organic carbon in recent 11 years based on bibliometric analysis
摘要
Abstract
In order to understand the research status and hotspot trends of soil organic carbon,based on bibliometric analysis,soil organic carbon as the main topic was searched in the core database of Web of science,and 891 relevant highly cited papers were selected as research data.VOSviewer software and Citespace software were used to quantitatively analyze the literature with soil organic carbon as the theme word.The results showed that:1)The highly cited literature showed an overall fluctuating trend from 2012 to 2022.2)Environmental science,ecology and multidisciplinary science were the main disciplines involved in soil organic carbon research,and multidisciplinary science had gradually become the main trend of research and occupying an important position in this field.3)Yakov Kuzyakov and the Chinese Academy of Sciences were the major contributors and institutions in the fields related to soil organic carbon research.The Chinese Academy of Sciences and Yong Sik Ok were the institutions and authors that cooperate most closely with other scientific research institutions and authors in this research field.4)Through the analysis of keywords and emergent words,the main research hotspots and development trends in this field mainly focused on the relationship between the change of soil carbon dioxide content and atmospheric greenhouse gas content and climate change,soil organic carbon sequestration and fixation in agricultural land use,and the influence of pyrolysis temperature on biochar.In general,in the context of global warming,research soil organic carbon remains a hot topic.In the future,more attention should be paid to the collaborative research between different environments and different regions,so as to further explore the impact of soil organic carbon change on climate change.关键词
